The solution to a lot of problems here are more high density housing. The way you get that is taxes and eminent domain to tear down and rebuild. But that will weaken current SF residents political power, so they fight against it. Pushing labor out of the city removes their power to affect change.
The only point I'd bring up about the tech industry is the SF residents putting up these barriers are often old time tech folks that "made it".
I think Seattle has some of the same issues, but at least seams to be handling things a lot better.
